Claims. ((1222-36) One of its principal uses is fori fuel used for vehicles not used on the highway for which l no sales tax is charged.

The register will record the amount of fuel 'pumped at each stroke of the piston regardless of whether it be a full stroke or a part stroke which is desirable because in a hand operated piston pump the piston is not always moved a full stroke.

The register is built as a part of the pump and is cheap, compact, and durable. It embodies various novel features of construction and arrangement, reference being had to the accompanying drawings in which:

Fig. l is a vertical elevation, with parts broken away, of a pump with the register attached,

Fig. 2 is a fragmentary elevation of parts of the pump with the register removed,

Fig. 3 s an enlarged elevation of the register with parts broken away,

Fig. 4 is a sectional elevation on the line 4-4 of Fig. 3, and

Fig. 5 is a fragmentary section showing parts of the register.

Like reference numbers refer to like parts in all of the figures.

The body 1 of the pump has an inlet chamber 2 and an outlet chamber 3 to which are connected the flow pipes 4- and 5. A cylinder 6 with a piston 7 is located within the body 1 and communicates with the inlet and outlet chambers 2 and 3 by one way valves 8 and 9, those shown being of the conventional ap valve type.

The piston rod 10 extends through a stuiing box 11 and projects outside the body 'where it is pivotally connected at 12 to a hand lever 13. The lower end of the hand lever 13 has a link connection with the body 1 of the pump by means of an arm 14 which is pivotally connected at 15 to said pump body, the arm 14 being an integral extension from the meter body 16 and the lower end of the lever 13 being pivotally connected with the rear side of said meter body 16 by a pivot pin 17. By this connection, the hand lever 13 reciprocates the piston rod 10 in a straight line while the lower end of the hand lever 13 oscillates in an arc about the pivotal connection 12.

The register body 16 is of shallow cylindrical shape having a bottom 18 and a circular side wall 19. A boss 20 projecting from the bottom 18 supports the pivot pin 17. A central boss 21 projects forwardly from the bottom 18 and has a bore 22 in which is rotatably mounted a shaft 23. The shaft 23 has fixed to it a ratchet disk 24, a pointer hand 25 and a knob 26. A dial 27 surrounds the shaft 23 forwardly of the ratchet disk 24 and the dial is detachably held in place on the circular side walt E9 by suitable attaching means such as a flat spring f depends upon the length of the stroke.

. 2 ring 28 biting into a groove in the sidewall. The dial 27 bears against a collar 29 on the shaft 23 and holds the shaft in place in the bore 22. Y

The ratchet disk 24 is spaced from the bottom 18 and in this space is a yoke 30 which is pivoted to the bottom 18 on a pivot pin 31. The yoke 30 has an opening 32` which surrounds the boss 21 with ample clearance for pivotal movement of the yoke. Near the lower swinging end of the yoke-30, and on its under side, a groove 33 is provided which extends radially from the pivot 31. A sliding block 34 is mounted in the groove 33, rthe block 34 being pivotally `attached to the end of a lstud 3S which is mounted on the hand lever 13 a short retaining pawl 39 is attached to the sidewall 19 and en-v gages the ratchet teeth 38 to prevent reverse movement of the ratchet disk.

In operating the pump, the hand lever 13 is oscillated in in and out movements which imparts like movements to` the piston rod 10 and piston 7. The out movement draws liquid into the cylinder through the inlet pipe 4, which is connected with a suitable source of supply, and the inlet chamber 2, the inlet valve y8 opening to permit passage of the liquid therethrough. On the in movement, the inlet valve 8 closes and the liquid is forced out of the pump through the outlet valve 9, the outlet chamber 3 and the outlet pipe 5 which leads to a suitable container such as the fuel tank of a tractor. The amount of liquid passed through the pump at each stroke of the lever This may vary because the lever 13, being hand operated, may not always be given the fu-ll length of its stroke.

As the `lever 13 is oscillated about its pivot pin 17, which connects it with the pumpbody 1 by the link arm 14, the stud 35 will oscillate about the pin 17 and with relation to the register body 16, moving in the arcuate slot 36. As the stud 35 oscillates in this arcuate movement, the block 34 moves with it, sliding in the groove 33 and causing the yoke 30 to swing about its pivot 31.

Swinging of the yoke 30 moves the operating pawl 37 about the pivot 31. The out movement of the lever 13, which draws liquid into the pump, moves the pawl 37 in counter clockwise direction in which it slides over the 4ratchetteeth 38. In the in movement of the lever 13, which forces liquid out of the pump and into the container, the yoke 30 is swung in the opposite direction in which the pawl 37 grips the ratchet teeth 38 and moves the ratchet disk 24 in a clockwise direction. As the ratchet disk 24 moves, the pointer hand 25 rotates with it, moving in a clockwise direction over the dial 27. The dial may be marked with the desired indicia such as gallons and fractions thereof, to indicate the quantity of liquid passed through the pump.

The ratchet teeth 38 should 'be a Very fine and close together so that small movements ofy the lever 13 will register on the dial. It is conceived that other one way clutch or gripping means may be substituted for the ratchet teeth and pawl herein shown.

If it is desired to reset the hand 25, yas for example to zero, the knob 26 may be rotated in a clockwise direction whichwill rotate the hand to the desired location on the dial, the pawls 37 and 39 sliding over the ratchet teeth 38 to permit such movement.

This register is economically constructed. Its body with the extending arm 14 serves as the connecting link between the lower end of the lever 13 and the pump body 1. It is an integral part of the pump structure and not Patented Aug. 27, 1957V a .Separate attachment thereto. .It serves `thrlpnrpose YOfc automatically indicating the quantity ofV liquid passed through the pump by manipulation of the 'hand lever, whether the..
